Some scapolite fluoresces yellow under ultraviolet light.

Specific Gravity of Minerals . Specific gravity is the density of a material, in this case a mineral, compared to an equivalent volume of water. If a piece of galena has a specific gravity of 7.58, that means that it is 7.58 times heavier than a volume of water identical to the volume of that particular piece of galena.

Density and Specific Gravity are not properties easily determined, requiring special equipment; but a result of them, which might simply be called "heft" can come in handy: The denser a mineral is, the heavier it is per given volume. A 1 inch cube of galena is noticeable heavier in the hand than a 1 inch cube of pyrite.

Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or modifications. ADVERTISEMENT 1.

Mar 14, 2023 · SG might also be used (as Archimedes did) to distinguish pure gold (SG = 19.3) from 14K gold (SG =13.3) or pyrite (SG = 5.1). Some specific gravities of minerals are shown below. Online mineral vendors sell equipment for determining specific gravity, but it is simple to do in the lab. Specific gravity is related to density, but it is unitless. For example, when pure galena is used to make a pseudo heavy liquid, a specific gravity of 4.3 is obtainable but the practical limit is about 3.3. Above this S.G. the viscosity of the suspension is too high to effectively deal with small particle sizes, particularly those particles that have a density close to that of the medium, also known as near …

As a consequence, gypsum typically occurs as layers associated with limestone, dolostone, shale, and rock salt.
